Using uvmhist without ddb?
Hello. I'm working on an issue with NetBSD-5 that may involve a problem with error paths in uvm. I'd like to use the uvmhist facilities in NetBSD to see if I can help track the issue down. However, the machine on which I'm doing this work doesn't support the convenient use of ddb(4). Is there a way to get uvm to print its statistical history without having to drop the machine into ddb? -thanks -Brian

Look at UVMHIST_PRINT. Eduardo
